The winners of the Royal Observatory Greenwich Annual Astrophotography Competition were announced in Sept 2023.
This year's overall top spot came from the Galaxies category—"Andromeda, Unexpected", titled for the large, blue plasma arc pictured next to our nearest galactic neighbor. The plasma streak is actually a new discovery and is now being studied by scientists as perhaps one of the largest phenomenon of its type anywhere in the known universe.
Winners in other categories include:

Skyscapes, winner: the extremely rare phenomena captured in this photograph are called sprites. Sprites occur like lightning, high in Earth's atmosphere, and are seldom witnessed from the ground. This photo was taken from an extremely high ridge in the Himalaya mountains of Tibet [credit: Angel An]
Skyscapes, runner up: time-lapse photography of star trails. The movement of the stars in the northern and southern hemispheres both appear to bend away from the stars moving along the celestial equator. [credit: Louis Leroux-Gere] {source: Space.com}
